Containers

Overview

Containers endpoints

Available Operations

list_container_files - List container files
get_container_file - Retrieve a container file
download_container_file_content - Download container file content

list_container_files

Lists the files under a sandbox session prefix, in lexicographic path order. A restarted session is a separate container with its own session id. Paginate with limit and after (pass the previous page’s last_id); has_more: true always means the next page is fetchable that way.

Example Usage

from openrouter import OpenRouter
import os


with OpenRouter(
    http_referer="<value>",
    x_open_router_title="<value>",
    x_open_router_categories="<value>",
    api_key=os.getenv("OPENROUTER_API_KEY", ""),
) as open_router:

    res = open_router.containers.list_container_files(session_id="sess-abc123", limit=100)

    # Handle response
    print(res)

Parameters

Parameter	Type	Required	Description	Example
`session_id`	str	:heavy_check_mark:	The sandbox session id, exactly as stored — a restarted session has its own `-r<nonce>`-suffixed id.	sess-abc123
`http_referer`	Optional[str]	:heavy_minus_sign:	The app identifier should be your app’s URL and is used as the primary identifier for rankings. This is used to track API usage per application.
`x_open_router_title`	Optional[str]	:heavy_minus_sign:	The app display name allows you to customize how your app appears in OpenRouter’s dashboard.
`x_open_router_categories`	Optional[str]	:heavy_minus_sign:	Comma-separated list of app categories (e.g. “cli-agent,cloud-agent”). Used for marketplace rankings.
`limit`	Optional[int]	:heavy_minus_sign:	Maximum number of files to return (1-1000). Defaults to 100 when absent.	100
`after`	Optional[str]	:heavy_minus_sign:	Forward cursor: a container file id from a previous page (typically `last_id`); listing resumes strictly after that file.	cfile_b3V0L3JlcG9ydC5jc3Y
`retries`	Optional[utils.RetryConfig]	:heavy_minus_sign:	Configuration to override the default retry behavior of the client.
